Walking the walk: a phenomenological study of long distance walking

Evidence suggests that regular walking can elicit significant psychological benefits although little evidence exists concerning long distance walking. The purpose of this study was to provide detailed accounts of the experiences of long distance walkers. Phenomenological interviews were conducted with six long distance walkers. Data were transcribed verbatim before researchers independently analyzed the transcripts. Participants reported a cumulative effect with positive feelings increasing throughout the duration of the walk. Long distance walking elicited positive emotions, reduced the effects of life-stress, and promoted an increased sense of well-being and personal growth. Results are aligned to theories and concepts from positive psychology

Design of supported cobalt catalysts with maximum activity for the Fischer-Tropsch synthesis

The role of the cobalt particle size distribution in the Fischer–Tropsch (FT) reaction for supported Co catalysts was investigated. Using TEM histogram analyses and activity measurements of carbon nanofibersupported catalysts, the TOF of discrete Co particle sizes was calculated. It was found that cobalt particles of 4.7 ± 0.2 nm are the most active in the FT reaction (1 bar, 220 C), and a narrow Co particle size distribution is clearly essential to arrive at the maximum activity. We have approached this requirement for maximum FT activity with an 18 wt.% Co/SiO2 catalyst prepared via impregnation, drying and calcination in NO/He. The more narrow Co particle size distribution (4.6 ± 0.8 nm) in Co/SiO2 led to an activity enhancement of 40% compared to Co/CNF (5.7 ± 1.4 nm), although some promoting effect of silica could not be excluded

Development of guideline-based indicators for patient-centredness in fertility care: what patients add

Item does not contain fulltextSTUDY QUESTION: What value can patients add to the development of guideline-based quality indicators for patient-centredness in fertility care? SUMMARY ANSWER: Infertile patients mainly select different indicators and value different dimensions of patient-centredness (e.g. information and communication and access to care) than professionals (e.g. coordination and integration of care) during an indicator development process. WHAT IS KNOWN ALREADY: Patient-centredness is an important dimension for the quality of fertility care. However, this dimension is not adequately evaluated by professionals, due to a lack of quality indicators. Furthermore, it is suggested that patients select different indicators for patient-centredness than professionals, although exact differences are unknown. STUDY DESIGN, SIZE AND DURATION: The RAND-modified Delphi method (a two-step systematic consensus method) was used to develop two sets of quality indicators for patient-centredness. Similarities and differences in the indicators as well as in aspects of patient-centredness between patients' and professionals' sets of indicators were analysed descriptively. PARTICIPANTS, SETTING, METHODS: The development of quality indicators for patient-centredness was based on the national multidisciplinary Network Guideline on infertility. Two panels participated: one patients' panel (n = 19) and one multidisciplinary professionals' panel (n = 15). MAIN RESULTS AND THE ROLE OF CHANCE: From 119 formulated potential indicators of patient-centredness, the patients' panel selected a representative set of 16, while the professionals' panel selected 18. Five indicators were included in both sets. These regarded the need to perform IUI at least 6 days a week; report on treatment outcomes and complications; report on results of semen analyses in a standardized way; counsel infertile couples about the positive effects on their chance of pregnancy of the elimination of a harmful lifestyle and provide information on the negative consequences for achieving a pregnancy in case of a high BMI. Both patients and professionals put highest value on potential indicators of information and communication in fertility care. Patients also emphasized accessibility of care, whereas professionals emphasized coordination and integration as important quality measures for patient-centredness in fertility care. LIMITATIONS, REASONS FOR CAUTION: First, the total number of developed indicators in the final set is relatively large (n = 29), which could be a first potential limitation in its use for accreditation and quality monitoring. Secondly, although panel members were asked to take reliability into account during the selection procedure, the indicators still need an evaluation of the measurability and the intra- and inter-observer reliability. WIDER IMPLICATIONS OF THE FINDINGS: The final guideline-based indicator set consisting of 29 indicators represents a balanced set that is based on the expertise of all stakeholders, including patients. A next step should be the application of this set in a future practice test to assess the feasibility in daily practice. In our opinion, most quality indicators for patient-centredness could be used for monitoring and improving the quality of fertility care internationally, occasionally by a more broad interpretation (e.g. by replacing the general practitioners with other healthcare professionals engaged in the care process). STUDY FUNDING/COMPETING INTEREST(S): This study was supported by a research grant (number 150020015) from the Dutch Organisation for Health Research and Development (ZonMw) in a research programme on broadening and acceleration in multidisciplinary guideline development.

Toward a multifaceted platform for humanitarian demining: Paper presented at 13th IARP Workshop on Humanitarian Demining and Risky Interventions, HUDEM 2015, Beograd, Croatia, 27-28 April 2015

The D-BOX project aims to increase deminers' confidence in technology developing a web-enabled platform which allows them to better utilize existing technologies and foster the development of the use of new ones. The idea behind D-BOX is to create an Information Management System which incorporates the process of Land Release, whereby the use of technologies is part of the process. The system will be flexible to adapt to local needs but at the same time it will be compliant with the IMAS. In a complex domain like demining, single technologies are rarely effective. The new platform will foster functional tool chains to realize complex tasks, information merging and synergies amongst heterogeneous tools to increase the effectiveness of the tool combinations. In the paper we establish the requirements for the new platform and give examples of Functional Tool Chain(s) and of Synergies among tools being developed by D-BOX partners
